BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to the field of wall paneling for application to one or more walls of a room to provide a decorative look and to protect the walls. More specifically the present invention relates to a modular wall paneling system and installation method for wainscoting and other wall covering applications. The wall paneling system is of a type which includes a plurality of rectangular wall panels each having a decorative front surface and a rear surface. A plurality of elongate upper and lower mounting rails each include a base adapted to be affixed horizontally along the walls end-to-end respectively at chair rail height and directly above the base board trim pieces. Top and bottom edges of the wall panels are respectively retained to the upper and lower mounting rails by attachment devices thereof which retain the wall panels to the walls. A plurality of elongate wall trim pieces attach over the upper mounting rails to provide a finished look. The wall paneling system may additionally include corner mounting rails, corner trim pieces, and corner caps to finish inside and outside corners of a room.

2. Description of the Prior Art

Traditional wall paneling systems include a plurality of wall panels made of a solid sheet of wood formed by gluing together and planing a plurality of individual wood boards to form panel sheets. The panel sheets are often stained and lightly waxed to enhance the appearance of the wood and form the finished wall panels. Alternatively, the panel sheets may be painted. The wall panels may further be milled with vertical grooves to simulate a plurality of individual wood planks and to hide joints between adjacent wall panels, or the joints may be covered by vertical stiles. The wall panels are nailed to the walls of a room or optionally glued thereto using conventional adhesives designed for that purpose in order to eliminate the nail holes. The wall panels may be of full height extending upwardly from the base board trim piece to a ceiling or crown molding trim piece. Alternatively, the wall panels may be of partial height extending from the base board trim pieces to a height of about three to five feet and terminating at a horizontal wall trim piece or chair rail for classical wainscoting. The chair rail is typically stained or painted to complement the paneling. While such wood wall panels look nice, they are expensive to produce due to the cost of the solid wood used in the construction thereof Additionally, skilled labor is required to make the wood boards into panel sheets, cutting the panel sheets to finished size, routing, sanding, staining, and waxing which further increasing the finished cost thereof Installation is typically done by a skilled carpenter due to the amount of cutting, fitting to the walls, and finishing required.

More recently designed wall panels are made from conventional plywood sheets covered by a thin hardwood veneer to lower the cost of the wall panels. This allows lower quality wood to be used in the construction of the plywood sheets which is covered by the thin hardwood veneer of high quality wood. While these wall panels are much less expensive to manufacture than the solid sheet type wall panels, installation by a skilled carpenter is still typically required.

There have been various wall paneling systems developed and patented in attempts to lower the cost of wall paneling systems and decrease the skill required for installation thereof. For example, a raised panel paneling system is disclosed in U.S. Pat. No. 4,736,559 issued on Apr. 12, 1988 to Young. The paneling system includes a plurality of paneling sheets securable to a substrate such as walls with respective side edges of adjacent sheets forming permissible gaps of from zero (i.e. paneling sheets abutting) to a predetermined maximum gap to minimize the amount of cutting needed to fit the paneling sheets to the walls. A chair rail is affixed to the walls over the paneling sheets to divide the paneling sheets into respective top and bottom. A plurality of stiles are affixed to the walls respectively covering the gaps between the adjacent paneling sheets. A plurality of base board trim pieces are affixed to the walls covering respective bottoms of the paneling sheets and a plurality of ceiling trim pieces are affixed to the walls covering respective tops of the paneling sheets. A plurality of moldings are affixed to the walls covering respective intersections of the chair rails and the stiles and joints which are mitered to provide a finished look for the paneling system. While the paneling system of Young may be easier to install due to less cutting of the wall panels being required, it still requires a relatively high skill level to install and is relatively costly to manufacture.

Traditional wall panels have further drawbacks, including limitation in available shapes and styles, lack of changeability of the wall panels without ruining the underlying walls upon removal. This is particularly problematic when the wall panels are affixed to the walls using adhesives and the edges are caulked to provide a more finished look at time of installation thereof These wall panels further typically require special tools for installation such as saws and saw guides due to the exact cuts which must be made to the wall panels to fit around doors, windows, electrical outlets, and the like. The wood construction of the wall panels is not environmentally friendly and is susceptible to mold and mildew damage particularly in wet environments. The wall panels are not readily cleanable due to the rough wood surface finish thereof and they are not durable, requiring periodic maintenance such as application of protective waxes or oils, repainting, re-caulking, and the like to maintain them.

Therefore, there is a continuing need for a modular wall paneling system which solves the problems with the traditional wall paneling systems and which provides additional benefits and features.

It is thus an object of the present invention to provide a modular wall paneling system which is of low cost to manufacture and easy to install.

It is another object of the present invention to provide a modular wall paneling system which is available in a wide variety of shapes and styles which may be mixed and matched at initial installation, which requires no adhesives or caulking of the edges of the wall panels and the trim pieces, and which may be changed without ruining the underlying walls.

It is a still further object of the present invention to provide a modular wall paneling system in which no special tools are needed for installation and which requires no exact cuts for the wall panels to fit around doors, windows, electrical outlets, and the like.

It is another object of the present invention to provide a modular wall paneling system which can be removed and reinstalled in another dwelling if so needed such as for apartment dwellers and other residents of rental property.

It is a still further object of the present invention to provide a modular wall paneling system in which mounting thereof does minimal damage to the walls and other building structure.

It is still another object of the present invention to provide such a modular wall paneling system in which virtually no preparation of the walls such as removal of the existing base molding rim pieces and ceiling trim pieces is required.

It is yet another object of the present invention to provide such a modular wall paneling system in which the wall panels may be easily interchanged following installation to change the entire look of the room.

It is still another object of the present invention to provide such a modular wall paneling system which is designed to be flexible enough to accommodate any size and shape of room including non-square corners and wavy or otherwise irregular walls.

It is yet another object of the present invention to provide such a modular wall paneling system which may be installed over virtually any type of wall including drywall, brick, concrete block, and previously installed paneling.

It is yet another object of the present invention to provide such a modular wall paneling system in which installation time is quicker than traditional wall finishing by paneling or painting.

It is a still further object of the present invention to provide a modular wall paneling system in which the wall panels are impact resistant and durable for use in highly abused rooms such as garages, children's rooms, offices, mud rooms, and foyers.

It is yet another object of the present invention to provide such a modular wall paneling system which is mold and mildew resistant for use in bathrooms and other wet areas.

Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure.

Reference is now made to the drawings, wherein like characteristics and features of the present invention shown in the various FIGURES are designated by the same reference numerals.

First Preferred Embodiment

Referring to FIGS. 1-8, a first embodiment modular wall paneling system 20 for application to at least one wall of a room, preferably in the form of wainscoting is disclosed. The wall paneling system 20 is shown as installed in a room 23 along a pair of walls 26 and 29 at an inside corner 32 of an angle “A” of ninety degrees above a floor 34 and a base molding 35, around window molding 36 of a window 37, and abutting door molding 38 of a doorway 39 surrounding a door 40. A “modular wall paneling system” for purposes of this application is understood to include not only wainscoting installations, but also other applications including but not limited to whiteboards, dry erase boards, chalkboards, cork boards, modular shelving, clothing racks, coat hooks, hat racks, photo or artwork frames, padded upholstered panels and picture or other artwork frames, and the like.

As best shown in FIG. 3, the modular wall paneling system 20 includes a plurality of generally flat members in the form of modular wall panels 41 each being of at least limited flexibility and preferably being semi-rigid, elongate upper mounting rails 44, elongate lower mounting rails 47, and elongate wall trim pieces 50 commonly referred to as a chair trim rails.

The wall panels 41 are preferably of the rectangular shape shown of a height “H”, though other shapes may be used which have flat sides such as triangles, octagons, and the like which allow attachment to the upper and lower mounting rails 44 and 47. The wall panels 41 are adapted for application to the walls 26 and 29 of the room 23, each including a front panel 53 with a front surface 56, an opposing rear surface 59 of a rearwardly convex shape formed by a plurality of parallel ribs 62 which create broken line contact with the walls 26 and 29 at respective collinear contact lines 63, and a peripheral edge 64 comprising a top edge 65, a bottom edge 68, a side edge 71, and a side edge 74. The ribs 62 stiffen the wall panels 41 for durability and create essentially point contact at the contact lines 63 with the walls 26 and 29. The wall panels 41 are adapted to be retained against respective of the walls 26 and 29 by the upper mounting rail 44 and the lower mounting rail 47 at opposite portions of the peripheral edge 64 comprising the top edge 65 and bottom edge 68 such that there is a slight amount of interference with respective of the walls 26 and 29. This causes the wall panels 41 to bow slightly outwardly at respective middle areas 80 thereof between the top and bottom edges 65 and 68 to take out any potential gap between the walls 26 and 29 and the wall panel 41 if the walls 26 and 29 are uneven. This allows the wall panels 41 to stay tight against the walls 26 and 29 and not rattle upon contact therewith or other situations such as when a door (not shown) is shut. Alternatively, the rear surface 59 may be of other rearwardly convex configurations which provide line contact with the walls 26 and 29. These include a curved planar rear surface 81 (FIG. 4 dotted lines) adapted for engaging the wall by creating unbroken line contact therewith or other curved configurations which provide limited contact with the walls 26 and 29.

As best shown in FIG. 4, the wall panel 41 preferably includes a first additional feature in the form of a panel edge joining device 83 in which the side edges 71 and 74 are of mutually interlocking design, each having respective interlockable halves of the panel edge joining device 83 to allow adjoining wall panels 41 to interconnect. The edge joining device 83 comprises of a tongue 86 integral with side edge 71 and a groove 89 integral with side edge 74. The tongue 86 and groove 89 preferably extend the length of the side edges 71 and 74 to ensure that the wall panels 41 are flush with each other from top edge 65 to bottom edge 68 even if the walls 26 and 29 are uneven such as by being wavy. The tongue 86 is mounted to the groove 89 by sliding downwardly thereinto. Alternatively, tongue 86 may be designed to snap-fit into groove 89 by pressing edgewise thereinto to slightly deflect side edge 74. The wall panels 41 may form a waterproof joint if so desired by being a tight fit or using an adhesive or sealant therebetween. The tongue 86 and groove 89 are rounded to provide easy sliding together and removal without using tools and without damaging the wall panels 41. Likewise, the components of wall paneling system 20 are rounded as needed so assembly and disassembly is done without damaging any component.

The wall panel 41 preferably includes a second additional feature in the form of a panel edge hiding device 90 wherein the side edges 71 and 74 include respective indent halves 92 and 95 of the panel edge hiding device 90. The indent halves 92 and 95 are each of quarter-round cross-section which form a full indent 98 of half-round cross-section at adjoining wall panels 41 to provide a finished look therebetween and to control any possible gap (not shown) between the wall panels 41 where the side edges 71 and 74 do not fit together exactly flush.

These materials, as well as other suitable aluminum, steel, or other metal, or other suitable materials, have a suitable combination of impact resistance, cost, limited flexibility, scratch resistance, and molding characteristics. The upper mounting rails 44, wall trim pieces 50, inside corner mounting rails 182, inside corner trim pieces 185, outside corner mounting rails 293, and outside corner trim pieces 296 are preferably made using a plastic or metal extrusion process due to the ability of such extrusion processes to make complex linear shapes at low cost. The wall panels 41, inside corner caps 188, and outside corner caps 299 are preferably injection molded from plastic polymer material. Secondary processes such as in-mold decorating, painting, anodizing, hydro-coloring, and the like may be used on all to achieve the desired colors and decoration thereon.

The modular wall paneling system 20, particularly the visible component parts such as the wall panels 41, wall trim pieces 50, inside corner trim pieces 185, inside corner caps 188, outside corner trim pieces 296, and outside corner caps 299 may be of a common genre such as a common functional design as in standard routed molding designs, an artistic design, or a theme. The common genre may be applied thereto using a process such as molding, printing, embossing, applying a decorative papering such as wall paper, or other conventional process. Examples include simulated wood, murals, a diamond plate pattern, a white beadboard, picture frame molding, faux brick, faux rock, camouflage, and upholstered padded panels for soundproofing or as soft walls for children's rooms or nurseries. Examples of licensed cartoon and other characters, corporate logos, and trademarks include such as Mickey Mouse, Dora the Explorer, Harley-Davidson, Ferrari, Spongebob Squarepants, Clifford the Big Red Dog, Winnie the Pooh, Barbie, Disney princesses, Bob the Builder, NASCAR, All sports teams, Movie themes, TV shows, and the like.

The modular wall paneling system 20 is installed by cutting to length and mounting the lower mounting rails 47 to respective of the walls 26, 29, and 305 just above the base molding 35 using the screws 107. The lower mounting rails 47 are mounted to the walls 26, 29, and 305 so as to just touch at the inside and outside corners 32 and 302. The upper mounting rails 44 are then cut to length and mounted to respective of the walls 26, 29, and 305 using the screws 107 at a measured height “H1” above the lower mounting rails 47 for the particular height “H” of the wall panels 41 to snap-fit to the upper mounting rails 44. The upper mounting rails 44 are mounted to respective of the walls 26, 29, and 305 spaced from the inside and outside corners 32 and 302 a distance “S” to allow room for the inside and outside corner caps 188 and 299. The inside and outside corner mounting rails 182 and 293 are then cut to length and respectively mounted to the walls 26, 29, and 305 at corners 32 and 302 using the screws 107. The corner mounting rails 182 and 293 are of a height “H2” which is the same as the distance to the bottom of the wall trim pieces 50 when installed which allows room for the inside and outside corner caps 188 and 299.

One or more of the wall panels 41, typically the endmost of panels 41, may be vertically cut to fit the particular walls 26, 29, and 305 so as to have respective of the side edges 71 and 74 spaced from adjacent of the walls 26, 29, and 305 at the distance “S” from the inside and outside corners 32 and 302. This is later covered by respective of the inside and outside corner trim pieces 185 and 296. The endmost of panels 41 are typically cut so that they roughly meet the end edge of the associated upper mounting rail 44. The cut doesn't have to be perfect or precise, as the corner caps 188 and 299 will cover the cuts.

The wall panels 41 are mounted to the upper mounting rails 44 and lower mounting rails 47 by inserting the bottom edge 68 thereof into pocket 149 of lower mounting rail 47 and rotating the top edge 65 towards respective of the walls 26, 29, and 305. The top edge 65 is pushed against the wedge end 134 of the second locking clip 122 of upper mounting rail 44 which deflects slightly to allow passing thereunder to lock top edge 65 in place. This snap-fit feature of upper mounting rails 44 easily and securely retains the wall panels 41 in an upright position against the walls 26, 29, and 305. The wall panels 41 are preferably retained against respective of the walls 26, 29, and 305 by the upper mounting rail 44 and the lower mounting rail 47 such that there is a slight amount of interference with respective of walls 26, 29, and 305 so the wall panels 41 bow slightly outwardly at the middle area 80 between the top and bottom edges 65 and 68. This is done to take out any potential gap between respective of walls 26, 29, and 305 and the wall panels 41 if the walls 26, 29, and 305 are uneven so the wall panels 41 stay tight against respective of the walls 26, 29, and 305 and not rattle upon contact therewith or when a door (not shown) is shut. The indent halves 92 and 95 of the adjoining wall panels 41 form the full indent 98 to provide a finished look.

After the wall panels 41 are mounted, the inside and outside corner trim pieces 185 and 296 are cut to length and mounted to respective of the inside and outside corner mounting rails 182 and 293 as described above. The corner trim pieces 185 and 296 are of the height “H2” which is the same as the inside and outside corner mounting rails 182 and 293 which allows room for the inside and outside corner caps 188 and 299. Respective of legs 227 and 230, and 347 and 350 of the inside and outside corner trim pieces 185 and 296 overlap the wall panels 41 to provide a finished look.

After the inside and outside corner trim pieces 185 and 296 are mounted, the wall trim pieces 50 are mounted by snap-fitting to the upper mounting rails 44 as described above. The inside and outside corner caps 188 and 299 are installed next. The inside corner caps 188 are installed by inserting the bottom plugs 266 and 267 into the open areas 275 and 278 of wall paneling system 20, and inserting the side plugs 284 and 287 thereof into the open areas 290 of wall paneling system 20. Each corner cap 188 abuts respective of the wall trim pieces 50 to provide a finished look and to concealing the cut ends of the upper mounting rails 44, the wall trim pieces 50, the inside corner mounting rails 182, and the inside corner trim pieces 185. The outside corner caps 299 are installed by inserting the bottom plugs 395 and 398 thereof into the open areas 401 and 404 of wall paneling system 20, and inserting the side plugs 407 and 410 thereof into the open areas 290 of wall paneling system 20. Each corner cap 299 abuts respective of the wall trim pieces 50 to provide a finished look and to concealing the cut ends of the upper mounting rails 44, the wall trim pieces 50, the outside corner mounting rails 293, and the outside corner trim pieces 296.

The modular wall paneling system 20 solves the problem of obtaining a finished look such as obtaining an exact cut for the endmost of wall panels 41 since the inside and outside corner trim pieces 185 and 296 cover the cut edges thereof. The finished look is further obtained by the cut ends of the upper mounting rails 44, the wall trim pieces 50, the inside and outside corner mounting rails 182 and 293, and the inside and outside corner trim pieces 185 and 296 being covered by the inside and outside corner caps 188 and 299.

Secondary processes such as in-mold decorating, painting, anodizing, hydro-coloring, and the like may be used on all to achieve the desired colors and decorations.

The modular wall paneling system 413 may be of various artistic designs or themes as described above for modular wall paneling system 20 wherein the whiteboard wall panels 434, and the horizontal and vertical wall trim pieces 449 and 452 are molded, printed, embossed, or otherwise adapted for such artistic design or theme. The whiteboard wall panels 434 preferably have any artistic design or theme is printed thereon rather than molded or embossed so the ink receiving layer 492 remains flat for writing and erasing thereon.

The modular wall paneling system 413 is installed by cutting to length and mounting the horizontal and vertical mounting rails 440 and 443 to the wall 419 centrally thereon using the screws 107 so as to just touch together. The horizontal mounting rails 440 are mounted such that the horizontal wall trim pieces 449 of the peripheral wall trim piece system 446 are at a vertical spacing “DV” such that the top and bottom edges 473 and 476 of the whiteboard wall panels 434 snap-fit between the wedge ends 542 of the horizontal mounting rails 440. The vertical mounting rails 443 are mounted such that the vertical wall trim pieces 452 of the peripheral wall trim piece system 446 are at a horizontal spacing “DH” such that respective side edges 479 and 482 of the wall panels 434 just clear the wedge ends 542 of the vertical mounting rails 443 to allow slight outward bowing of the wall panels 434 between the horizontal mounting rails 440 as described above without interference to the bowing from the vertical mounting rails 443. The horizontal and vertical mounting rails 440 and 443, and the horizontal and vertical wall trim pieces 449 and 452 are spaced at a distance “S2” from each other to allow assembly of the corner caps 455 thereto.

One or more of the whiteboard wall panels 434, typically the endmost of whiteboard wall panels 434, may be vertically cut to fit the particular size of modular wall paneling system 413 desired. The endmost of whiteboard wall panels 434 are typically cut so that they roughly meet the cut ends of the associated horizontal mounting rail 440. The cut doesn't have to be perfect or precise, as the corner caps 455 covers the cut ends.

The wall panels 434 snap-fit to the horizontal mounting rails 440 by inserting the bottom edge 476 thereof under the wedge end 542 of the second locking clip 530 of the lowermost of horizontal mounting rails 440 and rotating the top edge 473 towards the wall 419. The top edge 473 is pushed against the wedge end 542 of the second locking clip 530 of the uppermost of horizontal mounting rails 440 which deflects slightly to allow passing thereunder to lock top edge 473 in place. This snap-fit feature of the mounting rails 440 easily and securely retains the whiteboard wall panels 434 in an upright position against the wall 419. The whiteboard wall panels 434 fit between the wedge end 542 of the second locking member 530 of the vertical mounting rails 443 without deflecting due to the larger spacing “DH”. This allows the whiteboard wall panels 434 to preferably be retained against the wall 419 by the horizontal mounting rails 440 such that there is a slight amount of interference with the wall 419 so the wall panels 434 bow slightly outwardly at the middle area 488 between the top and bottom edges 473 and 476. This is done to take out any possible gap between the wall 419 and the whiteboard wall panels 434 if the wall 419 is uneven so the whiteboard wall panels 434 stay tight against the wall 419 and not rattle upon contact therewith or when a door (not shown) is shut. The indent halves 500 and 503 of the adjoining wall panels 434 form the full indent 506 to provide a finished look, or may be omitted if desired to provide easier writing thereon. Alternatively, the vertical mount rails 443 may be spaced closer together to allow all of the horizontal and vertical mounting rails 440 and 443 to grip the wall panels 434 by bowing the whiteboard wall panels 434 in two planes.

After the wall panels 434 are mounted, the horizontal and vertical wall trim pieces 449 and 452 are cut to length and mounted by snap-fitting to respective of the horizontal and vertical mounting rails 440 and 443 as described above. The corner caps 455 are installed next by snap-fitting to respective of the horizontal and vertical mounting rails 440 and 443 as described above. Each corner cap 455 abuts respective of the horizontal and vertical wall trim pieces 449 and 452 to provide a finished look and to concealing the cut ends of the horizontal and vertical mounting rails 440 and 443, and the horizontal and vertical wall trim pieces 449 and 452.

The modular wall paneling system 413 solves the problem of obtaining a finished look such as obtaining an exact cut for the endmost of wall panels 434 since the vertical wall trim pieces 452 cover the cut edges thereof. The finished look is further obtained by the cut ends of the horizontal and vertical mounting rails 440 and 443, and the horizontal and vertical wall trim pieces 449 and 452 being covered by the corner caps 455.

A method of the present invention of installing a modular wall paneling system for application to at least one wall of a room, comprises the steps of: 1) providing at least one wall panel of at least limited flexibility having a front surface, an opposing rear surface, and a peripheral edge, the rear surface being of a rearwardly convex shape of a configuration which provides line contact with the wall; and 2) restraining opposite portions of the peripheral edge of the wall panel against the wall in an upright position such that there is a slight amount of interference with the wall so the wall panel bows slightly outwardly at a middle area thereof to take out any gap between the wall and the wall panel.

The method may additionally comprise the steps of: 4) providing at least one elongate upper mounting rail having a base adapted to be affixed along the wall and an attachment device adapted to retain the peripheral edge of the wall panel to the wall; 5) providing at least one elongate lower mounting rail having a base adapted to be affixed along the wall and an attachment device to support the wall panel and retain the peripheral edge to the wall; 6) securing the lower mounting rail to the wall; and 7) securing the upper mounting rail to the wall at a measured distance above the lower mounting rails for the particular height of the wall panels to snap-fit to the trim mounting rails.

The method may be conducted wherein the wall panel provided is of a rectangular shape with the peripheral edge comprising a top edge, a bottom edge, and a pair of side edges, and wherein the step of restraining the wall panel against the wall includes engaging the bottom edge of the wall panel with the lower mounting rail and pivoting the top edge into engagement with the upper mounting rail. The attachment device of the upper mounting rail provided may comprise an elongate locking clip which extends from the base thereof adapted to resiliently snap-fit to the top edge of the wall panel. The attachment device of the lower mounting rail provided may comprise an elongate L-shaped member which extends outwardly from the base thereof to form an elongate channel defining a pocket therebetween to receive the peripheral edge of the wall panel. The engaging the bottom edge of the wall panel with the lower mounting rail may comprise inserting the bottom edge of the wall panel into the pocket of the lower mounting rail. The pivoting the top edge into engagement with the upper mounting rail may include pushing the top edge past the locking clip which deflects slightly to allow passing thereunder to lock the top edge in place.

Many modifications to the present invention are possible while staying within the same inventive concept. For example, the modular wall paneling system may be adapted for use on forty-five degree inside and outside corners, and corners of other angles. Various attachment devices may be used to attach the modular wall panels to the mounting rails other than the snap-fit type and/or directly to the walls such as patches of hook and loop fasteners commonly sold under the trade name Velcro™, magnets or magnetic strips, double-side adhesive tape, liquid adhesives, and snap-fit type pins or hooks. One or more of the various component parts of the wall paneling system may be molded together such as the wall trim pieces with the wall panels and the like. Other materials may be used besides pure polymer plastic materials such as wood, wood products, cement board, ceramic, and metals such as aluminum, stainless steel, and the like. Other exemplary materials include polymer composites such as a polymer with reinforcing fibers of glass, graphite, wood, flax or other such material. Yet other exemplary materials include a water resistant material such as pressed particle board which is wood particles impregnated with a resin that is subsequently covered with a waterproof surface layer such as paint, a sheet of polyethylene, polypropylene or polyvinyl chloride, or a thermosetting laminate. The wall panels may be attached together using other tongue and groove designs, pins (both for vertical and horizontal attachment), lap joints, C-type channel hooks, and the like. Other designs of ribs may be used which stiffens the wall panel and which function as described above. The ribs may be replaced by pins, suitably shaped spacers, foam or rubber blocks, and the like. The wall paneling system may extend from floor to ceiling by extending the height of the wall panels with or without using the horizontal wall trim pieces (chair rail) intermediate the floor and the ceiling. The wall paneling system may be available as kits designed to fit predetermined room sizes including wall lengths and heights, door frames, window frames, and the like. The wall panels may have the tongue and groove molded integrally therewith or separate pieces affixed thereto. The tongue and/or the groove may be coated or impregnated with an adhesive such as any commercially available two part micro-encapsulated epoxy which rupture and harden automatically upon assembly together or other adhesive, or a waterproofing material to assure no water passes therebetween. The component parts may be of different colors, designs, and the like which are mixed and matched as desired upon initial installation and which may be subsequently rearranged to change the look of a room.

The modular wall paneling system, wall panels, and method of the present invention solve all of the above-enumerated objectives. The system is of low cost to manufacture due to the plastic construction and easy to install due to the snapfit design thereof. The wall panels are available in a wide variety of shapes and styles which may be mixed and matched at initial installation and subsequently. The system requires no adhesives or caulking of the edges of the panels and the trim pieces due to the use of nails to affix the mounting rails to the walls and the covering of the cut edges which would normally require caulking. The snap-fit features allow changing of the wall panels and other snap-fit components without ruining the walls. The system requires no special tools for installation, only a hammer, tape measure, pencil, and saw to do only minimal cutting. The system is more environmentally friendly by using plastic rather than wood products to preserve the forests. The system may be made from recycled plastic or made to be biodegradable such as by adding starch or other ingredients to the plastic material. The plastic material used is inherently not susceptible to damage from mold and mildew in wet environments. The plastic material requires no painting or cleaning except occasional wiping with a damp cloth to remove dust. The entire wall paneling system can be removed and reinstalled in another dwelling if so needed by removing the nails which hid the mounting rails. The nails do minimal damage to the walls and no adhesives are used for installation which can cause substantial damage thereto. There is virtually no preparation required of the walls required, the system fitting around the existing base moldings and other trim pieces which need not be removed. The snap-fit features allow the wall panels to be easily interchanged to change the entire look of the room. The system accommodates any size and shape of room including non-square corners and wavy or otherwise irregular walls and may be installed over virtually any type of wall including drywall, brick, concrete block, and previously installed paneling by using appropriate fasteners other than conventional nails as appropriate, such as concrete nails, screws and anchors, and the like. The installation time is quicker than traditional wall finishing due to the use of nails for affixing the mounting rails to the walls and by requiring no subsequent finishing such as staining or painting. The plastic material is impact resistant and durable enough for use in highly abused rooms, and is ideal for bathrooms and other wet areas due to the inherent resistance of the plastic material to mold and mildew. The system is environmentally friendly by using no wood or wood products and capable of using recycled or biodegradable plastic.
